FIRE-ALARM.

SPECIFICATION formingpart of Letters Patent No. 253,297, dated February 7, 1882.

Application filed December 31, 1881. (No model.)

5 Ohio, have invented a new and useful Improvement in Fire-Alarms. and Fire-Extinguishers, of which the following is a specification.

My invention relates to devices used in that to class of tire-alarms and fire-extinguishing apparatus operated by the melting of fusible connections. I have found by experience that it is very objectionable to have these connections carried through a building in an exposed conas they are liable to be damaged. Moreover, wires are generally used for making said connections, which are very expensive.

The nature of my improvement consists in making these connections with lines of ordieach section being joined by fusible coupling-links; and my improvement further consists in inclosing said lines with thin metallic tubes, entirely closed except at such parts where the fusible coupling-links appear.

Referring to the accompany ing drawings,in which similar letters of reference indicate like parts, Figure 1 1s a tube partly broken away,

with inclosed linked twine, embodying my invention. Fig. 2 is a longitudinal sectional view thereof.

under side, forming openings to. B is a common cord within said tube, divided into sections of required length, the several sections being coupled together with fusible links 0, having eyes 0, through which the terminal ends of the several sections are fastened. It is manifest that when by the rise of temperature any one of the fusible coupling-links O is melted the tension of the cord will be withdrawn and any form of device to which it is connected will be operated.

Having now fully described my invention, what I claim is In an automatic fire-alarm or fire-extinguisher actuated by rupture of fusible connections, a cord divided into scctionallengths, the several sections being joined by fusible coupling-links inelosed within a tube having under openings coincident with the fusible links, substantially as described.
